9V claims. i (ol. ico- 328) This inventionA relates tovbrackets in -generah and rmore speciiical'ly f to. f hcldciownabrackets f :lor

releasably :securing the free endof .framelessI window: screens to` a: windowl sill.

:',fOne of: the prime objects. of: the:v invention is; to

desigma veryr simple, practical", .and inexpensive bracket/which cani bei readily manufactured ,and assembled` andfwhichscan be. formed `of stampings so that it lends itself to mass production.

Another` Objectis; to design an easily operable, compact, holddown bracket having screen bar guiding and holdingmeans formed integral therewith, iorrguiding the screen bar andreleasably locking it in position. i

A further object `is to design a holddown bracket formedwith slotted -openings'to accommodatetthe locking lever and :to permit i-tto be swungfgto fully locked position.

To the Yaccomplislnnent ofxtheforegoingand related \ends said invention thenconsistsfwoffthe meansf'hereinafter Vfully described,l and g particu.- larly pointed out in the claims, the annexed drawing and following description setting forth, in detail, certain means and one mode of carrying out the invention, such disclosed means and mode illustrating, however, but one of various ways in which the principle of the invention may be used.

In the drawing:

Fig. 1 is a fragmentary view showing my holddown bracket mounted on a window sill and associated with a frameless window screen, the solid lines showing the bracket in locked position 'and the broken lines showing it in unlocked position.

Fig. 2 is a perspective view of one of my hold-` down brackets, with the locking lever in raised position.

Fig. 3 is a view similar to Fig. 2 showing the locking lever swung down to locked position.

Fig. 4 is a side-elevational View, the locking link being shown in section.

Brackets of the type shown in the instant application must be light, smooth, easily operable, and of neat and pleasing appearance, because they are mounted in places where they are clearly visible; fabrics come into contact therewith, and they must be easily operable by the housewife, cleaners, and others working around and in connection with windows and screens, and I have,

therefore, designed a stamped bracket, streaml lined in appearance, and which is readily and easily operable when desired.

Referring now to Fig. 1 of the drawing in which I have shown a fragmentary portion of a window frame W, the frame opening being closed by a 2 framelessrscreen r S f havin bar 5 seuredonthepflower end-thereof.. andgwhi'ch is L-,adapted forfreleasable@engagement by fthe:

vL'Ihebracket B is; preferably; butV notV necessarily,

The locking lever I2 is also in the form of a stamping; it is U-shaped in cross section, with the lower end flatted as at I3 for easy engagement by the fingers of the operator. The inner end of the lever is bifurcated as at I4 and a pin I5 serves to pivotally connect the lever to the upper end of the wing 6 of the standard.

The stamped locking link II is hingedly connected to the locking lever I2 at a point spaced from the pin I4 by means of the pin I6, and a similar pin I1 connects the lower end of the link to the wing section 6 of the body, said pin being mounted in a vertical slot I8 formed in said wing to provide for the necessary vertical movement of the pin when the lever is swung to move the link into engagement with the clip.

The lower end of the link II is bent outwardly as shown and forms a jaw section 20 which is adapted for engagement with the clip I0 when the members are in assembled relation, and the -lever is swung down to locking position, the bar 5 being forced down into tight insect and weather-proof engagement with the sill L of the window.

A transversely disposed channel 2| is formed in the wing 6 of the standard, and accommodates the pin I6 when the lever I2 is swung to fully locked position, and as clearly shown in Fig. 3 of the drawing.

Screw openings 22 are provided in the walls of the U-shaped section of the bracket to facilitate mounting it in position, the leg 9 of the U-shaped portion permitting insertion or removal of the bar 5 when the lever is in raised position.

While in the instant application I have shown the bracket associated with a frameless Window screen, it will be understood that this is for explanatory purposes only as the bracket can be used to secure other articles as desired.

From the foregoing, it will be obvious that I have perfected a very simple, practical, economical andv neat-appearing holddown bracket for holding and releasably locking frameless window screens and similar articles in position.

What I claim is:

1. A holddown bracket of the class described comprising vertically disposed body portion mounted on a support formed 'with an oifset the upper end thereof, a vertical slot in said standard, a link pivotally connected to said lever at a point spaced from the pivot point of the lever with its lower end slidably mounted in said slot, and a jaw formed on the lower end of said link for engagement with the member to be secured when the locking lever is swung down.

6. lThe combination as defined in claim 5 in which the standard is angular in cross vsection and the locking link is U-shaped to accommodate one Wing of the standard therebetween.

.U-shaped section adapted to accommodate a Ya link assembly pivotally mounted on said body and engageable with said member for locking it when the lever is swung to locked'position.

2. The combination as defined in claim 1 in which the link is pivotally connected to the locking ylever at a point spaced fromthe pivot point thereof, and has slidable engagement with said body, said lever forcing the end of the link into engagement with said member when the lever is swung down.

3. The combination as definedin claim 1 in which a horizontally disposed slot is provided in thebody portion to facilitate full locking movement of the locking lever.

4. The combination as defined in claim 1 in which the U-shaped section automatically holds the article to be secured in cooperative relation with the locking link of the holddown bracket.

5. A holddown bracket of the class described comprising, a stamped standard havingV a U-shaped section formed integral therewith and adapted to accommodate a member to be secured, a stamped locking lever pivotally connected to' 7. The combination as set forth in claim 5 in which the outer leg of the U-shaped section is shorter to facilitate insertion of the member to be secured.

'8. The' combination as defined in claim 5 in which the link is- U-shaped in cross section with the lower end of one of the legs bent laterally to 9. A holddown bracket of the Iclass described, comprising, a vertically disposed body member angular in cross section and forming wings, a locking lever secured to the upper end of one of said wings, a locking link pivotally secured to said lever at a point spaced from said pivot point, with its lower end slidably connected to said wing, and an oiset jaw formed on the lower end of said link for locking engagement with a member to be secured.
